Lucianus Samosatensis, L.F. Philostratus, Callistratus Grammaticus. Owned by Manuel Chrysoloras; f. 509v has a scolium signed «L.A.» on the attribution of a poem to Callistratus. Pontani believes that «L.A.» is «da intepretare senz’altro come “Leonardus Aretinus”», but does not pronounce on the issue whether the note is autograph or merely reports Bruni’s opinion.
